PORTABLE INCINERA'TORUWITH REMOVABLE REFUSE CONTAINER BRIEF DESCRIPTION OF THEINVENTION An object of the invention is to provide a tor which can be easily loaded.

Another object of the invention is to provide a portable incinerator which is hi'ghly mobile and easy to operate.

A further object of the invention is to provide a portable inportable incineracinerator with a 'readily removable combined burning chamber and refuse container whereby in areas where burning is not permitted, an empty container'can be substituted for other containers as they become filled. 1

A still further object of the invention is to provide an incinerator with a combined burning chamber and refuse container from which ashes and the like can be readily dumped.

Other objects of the invention arefto provide inexpensive, durable and safe incinerators.

Briefly, the present invention comprises a triwheeled portable incinerator having a frame which carriers a combined burning chamber and refuse container and a scoop. The burning chamber is carried on rollers whereby it can be readily removed from the incinerator and'replaced by another. In addition, the floor of the burning chamber is provided with dumping plates to facilitate the removal of ashes from the chamber. The scoop is pivotally mounted on the frame and can be pivoted from a lowered position where refuse can be easily loaded into the scoop to a raised position where refuse can be discharged from the scoop into the burning chamber. In the raised position, the scoop serves as a cover for. the burning chamber.

The above-mentioned objects and advantages of the present invention will be more apparent "and other objects and advantages of the invention will be obvious from the following detailed description of the invention when taken in conjunction with the accompanying drawings in which:

DETAILED DESCRIPTION or 'll-IE INVENTION Referring now to the drawings and, in particular, to FIGS. 1 I to 3, the portable incinerator of the present invention, in- I dicated by reference numeral 10, comprises a triwheeled carriage 12 a combined burning chamber and refuse container 14, and a scoop 16. While preferably the incinerator is made with such materials and of such a sizeas to be easily movable by an individual, it is to be understood that the incinerator can be of any size desired. In addition, although not shown, it is contemplated that the incinerators can be self-propelled.

In the preferred form, the rigid frame of the triwheeled carriage 12 is made of square tubing or. comparable frame members which are secured together by welding, bolt assemblies or similar fasteners. The frame has a rectangular base comprising lateral frame members 20,22, front member 24 and. rear member 26 which, as shown, are welded together as are the other frame members of the incinerator. Extending diagonally upward and outward from each endof front member 24, are a pair of struts 28,30 which interconnectbase frame member 24 with an upper front frame member 32. Extending diagonally 2 I upward from each end of rear member 26 are a pair of struts 34,36 which interconnect member 26 with vertical frame members 38,40. Members 38,40 are, in turn, interconnected at their upper ends by means of an axle 42 as will be explained carriage 12 is mounted on a wheel52 which is centrallylocated with respect to the forward end of the carriage. Wheel 52 is rotatably carried on an axle 54that extends through and is retained in apertures located adjacent the free end of a fork member 56. Fork member 56 has a substantially vertically-extending axle, which is rotatably mounted in bracket 58, that has a plate 60 which is welded to frame members 24,32. With this construction, wheel 52can be pivoted thus enabling the carriage 12 to be easily guided during use.

A removable towing arm 62 is pivotally mounted on axle 54 by means of a yoke 64 having a hollow stem within which the lower end of the tubular towing arm is received. The towing arm 62 and the stem of the yoke 64 are provided with apertures that become aligned when the towing arm is in place so that a removable pin 66, or similar fastener, can be passed I through the apertures to secure the arm and yoke together, A detachable chain 68, or similar means, extends between the arm 62 and bracket 58'to normally maintain the towing arm in a raised position as shown in FIG. 1, Of course, if it is desired to lower the towing arm 62, chain 68 can be removed. Also, the towing arm 62 can be detached from yoke 64 and replaced by an attachment for connecting the incinerator to a lawn vehicle.

As best shown in FIGS. 1 and 3, each side of the carriage frame is provided with a pair of horizontally-extending spaced-apart mounting bars 70,72 which extend between and are welded to the inner surfaces of frame members 28,34 and slidably mounted on axles extending through apertures in the bars whereby the rollers rotate about a horizontal axis. The spacing between the rollers isequidistant with the rollers being utilized to support the combined burning chamber and refuse container 14 so that thecombined burning chamber and refuse container tor.

The combined burning chamber and refuse container 14 can be easily removed from the incineracomprises a pair of wire mesh sidewalls 76 (only one of which 7 is shown), a wire mesh forward wall 78, a wire mesh rear wall 1.

and a sheet metal floor 82. In the preferred form, sidewalls 76 are trapezoidal in configuration, while end walls 78 and 80 I are rectangular. Due to the this configuration, the horizontal cross-sectional area of the container is greater at the top than at the base of the container 14. f

The frame of the combined burning chamber and refuse container 14 is made of anglemembers with corner angle members 84, 8 6, 88 and 90 extending between and interconnecting upper horizontal frame members 92, 94, 96 and 98 with lower horizontal side frame members 100,102 which also serve as tracks for rollers 74'(see FIG. 3). The peripheral edges of the wire mesh panels are welded or otherwise suitably secured to the frame members and floor 82 of the combined burning chamber and refuse container 14 thereby forming the side and end walls of the container. Upper frame members 96 and 98 are each provided with handles to facilitate the insertion or removal of the combined burning chamber and refuse container 14 from the carriage 12 while frame member 86 carries a pivotal locking plate 104 that cooperates with a plate 106 (having a notch in its upper-edge) which is mounted on carriage frame member 38 toprevent relative movement of the burning chamber 14 relative to the carriage'lZ.

The sheet metal floor 82 is welded or otherwise secured around its upper periphery to angle frame members 100,102 (see FIG. 3) and wire mesh panels 78,80. The sidewalls 108,110, and end walls 112,114, of floor 82 are inclined inwardly from frame members 100,102 and wire mesh panels 78,80 and these walls combine with a longitudinally-extending inverted V-shaped partition 116 which extends between end walls 112,114 to form a pair of longitudinally-extending hoppers 118,120 which are open at the bottom.

The openings in the hoppers 118,120 are closed by a pair of dump plates 122,124 having upturned peripheral flanges which conform to the outer surfaces of the side and end walls 108, 110, 112, 114 of the floor 82. These dump plates are mounted on pairs of hinges 126 and 128 which are welded to the ends of the dump plates. As best shown in H0. 4, the pairs of hinges 126,128 are, in turn, mounted on a shaft 130 which extends the entire length of the floor'82. This shaft 130 is rotatably retained in a tube 132 which is secured to the underside of the floor 82 by means of triangular mounting plates 134,136 which are welded to the lower surfaces of the inverted V-shaped partition 116. As can be seen in FIGS. 1 and 3, the hinges 126 and 128 slide along the inclined end walls 112,114 of the floor 82. Hinges 126 are provided with a pair of operating levers 138 for pivoting the dump plates from a closed position, as shown in solid line in FIG. 3, to an open position, as shown in phantom line in FIG. 3. In addition, the end wall 112 is provided with a pairof locking lugs 140 for maintaining the dump plates in closed position. ln order to move levers 138 past the locking lugs 140, the levers 138 must be flexed outwardly. From the above, it can be seen that the removal of ashes from the burning chamber 14 is greatly facilitated by means of the hinged dump plates of the present invention.

Scoop 16 is pivotally mounted on carriage 12 by means of hinge plates 150 which have transverse sleeves 152 that are rotatably carried on axle 42 of the carriage. The scoop 16 comprises a pair of wire mesh sidewalls 154 having a triangular configuration (only one of which isshown) joined by a'pair of wire mesh intermediate walls 156,158. While wall 156 has been shown made of wire mesh, his to be understood that the wall can be made out of sheet metalor with an asbestos sheet if a fire wall is desired between the scoop 16 and burning chamber 14 when refuse is being loaded into the scoop.

The frame of the scoop 16 comprises inclined sidewall angle members 160,162 and 164,166 interconnected by a transverse angle member 168 and transverse bars 170,172. In addition, angle members 160,162 and 164,166 are provided with horizontal and vertical sidewall bracing bars 174 and 176, respectively, which further strengthen the sidewalls of the scoop. The peripheral edges of the wire mesh panels 154,156 and 158 are welded or otherwise rigidly secured to the frame members of the scoop. Y

As can be seen in FIGS. 1 through 3,since the hinge joint of the scoop 16 is located on the carriage frame at a point spaced above the upper edge of the burning chamber 14, the wire mesh of panels 154 and 156 extendbelow scoop frame members 172 and 174 so that when the scoop 16 is in its raised position, the wire mesh of the scoop extends down to the upper edge of the burning chamber 14; As shown, wire mesh panel 158 does not extend below frame member 170 so that when the scoop is in itslowered position, the refuse can be easily rakedor otherwise loaded into the scoop. However, it is contemplated that a hinged panel could be secured to frame member 170 which, due to gravity, would pivot to close the opening when the scoop is in its raised position and pivot down when the scoop is in its lowered position to thereby completely enclose the burning chamber in its upper position and stillallow the scoop to be loaded easily.

As shownlin H08. 1 and 2, the sides of the scoop 16 are provided with handles 178 which are rigidly secured to the frame of the scoop adjacent the juncture of frame members 174,176. In addition, the sidewall frame members are provided with stop plates 180, adjacent the hinge joint, which have outwardly extending flanges that cooperate with carriage frame members 44 and 46 to properly position the scoop 16 relative to the burning chamber 14. Due to the added stresses placed on the scoop frame in the region adjacent the stop plate and hinge joint, gusset plates 182 are interposed between and welded to the frame members of the scoop adjacent the joint for added strength.

OPERATION In operation, the scoop 16 can be pivoted from the raised position, shown in solid line in F16. 1, where it serves as a cover for the burning chamber 14 to a lowered position, as shown in phantom line in FlG.'-1, where leaves and other .refuse can be easily loaded into' the scoop. As shown, the

in solid line in FIG. 1 wherein the refuse in the scoop is discharged into the burning chamber or refuse container 14.

1f burning is not permitted in the area where the present invention is to be used or if for some other reason it is desired to remove the combined burning chamber and refuse chamber 14 from the carriage, this can readily be done by unlatching lock 104 and sliding the container, 14 out the rear end of the carriage 12. Of course, as discussed above, if it is merely desired to dump-the ashes from the container, levers 138 can be pivoted to the substantially vertical position shown in H6. 3 thereby lowering the dump plates and allowing the ashes to fall from the hoppers of the chamber 14.

While the floor 82 of the container 14, as shown and described, is not lined with asbestos, it is contemplated that the floor could be lined with asbestos'if desired. However, it has been found that such a lining is unnecessary since insufficient heat is radiated from the bottom .of the incinerator to set refuse beneath the incinerator on fire. In addition, it is contemplated that the diameter of the wheels and the size of the incinerator can be varied as desired.

While the preferred form of the invention has been shown and described, it is to be understood that all suitable modifications and equivalents may be resorted to which fall within the scope of the invention as claimed.
